Co-Occurrence Of Recurrent Migrainous Headaches And Transient Global Amnesia Following Minor Head Trauma: A Case Report, Aziz Badruddin Sonawalla, Saadia Arshad, Shafaq Saleem

Pakistan Journal of Neurological Sciences (PJNS)

A 32-year-old male, with a history of recurrent throbbing headaches, presented with three episodes of minor trauma to the head followed by throbbing headaches and blurred vision. In two of these episodes, he also had clinical features suggesting the occurrence of transient global amnesia (TGA) at the same time. Although migraines as well as TGAs are reported to occur following minor head trauma, the simultaneous occurrence of both is rather unusual and would support the fact that spreading depression is the main pathophysiological mechanism underlying TGAs as it is for migraines. We report an unusual case of migraine and TGA …

Faculty, Staff and Student Publications

Boron is an essential microelement for plant growth. Tomato is one of the most cultivated fruits and vegetables in the world, and boron deficiency severely inhibits its yield and quality. However, the mechanism of tomato in response to boron deficiency remains largely unclear. Here, we investigated the physiological and molecular bases of the boron deficiency response in hydroponically grown tomato seedlings. Boron deficiency repressed the expression of genes associated with nitrogen metabolism, while it induced the expression of genes related to the pentose phosphate pathway, thereby altering carbon flow to provide energy for plants to cope with stress. Boron deficiency …

Gross, Michael R. Sperling, Gregory A. Worrell, Sameer A. Sheth, Paul A. Wanda, Daniel S. Rizzuto, Michael J. Kahana

Department of Neurology Faculty Papers

Closed-loop direct brain stimulation is a promising tool for modulating neural activity and behavior. However, it remains unclear how to optimally target stimulation to modulate brain activity in particular brain networks that underlie particular cognitive functions. Here, we test the hypothesis that stimulation's behavioral and physiological effects depend on the stimulation target's anatomical and functional network properties. We delivered closed-loop stimulation as 47 neurosurgical patients studied and recalled word lists. Multivariate classifiers, trained to predict momentary lapses in memory function, triggered the stimulation of the lateral temporal cortex (LTC) during the study phase of the task. We found that LTC …

Faculty, Staff and Student Publications

Background: The clinical diagnosis of manifest Huntington's disease (HD) relies on a high level of clinical confidence (99% confidence) of HD-consistent motor signs. Longitudinal data have reliably identified cognitive and behavioral dysfunction predating clinical motor diagnosis by up to 15 years. Reliance on motor signs to establish a diagnosis of HD increases risk of early misdiagnosis or delayed diagnosis. Clinical neuropsychologists are uniquely positioned to advise on the clinical application of the Movement Disorder Society Task Force's recently proposed non-motor diagnostic criteria for HD.

Objectives: To provide (1) a recommended clinical approach toward non-motor diagnostic criteria in persons with HD …

Behavioral Or Neuropsychiatric Symptoms Of Alzheimer’S Disease: From Psychopathology To Pharmacological Management, Antonio Lucio Teixeira, Natalia Pessoa Rocha, Jennifer Gatchel

Faculty, Staff and Student Publications

Neuropsychiatric or behavioral symptoms of dementia encompass a series of disorders, such as anxiety, depression, apathy, psychosis, and agitation, all commonly present in individuals living with dementia. While they are not required for the diagnosis of Alzheimer's disease (AD), they are ubiquitously present in all stages of the disease, contributing to negative clinical outcomes, including cognitive decline, functional disability, and caregiver burden. Neuropsychiatric symptoms have been conceptualized not only as risk factors but as clinical markers of decline along the AD spectrum. The concept of "mild behavioral impairment", the behavioral correlate of mild cognitive impairment, has been proposed within this …

Faculty, Staff and Student Publications

Objectives

Sudden unexpected death in epilepsy (SUDEP) is a leading cause of death for patients with epilepsy; however, the pathophysiology remains unclear. Focal‐to‐bilateral tonic–clonic seizures (FBTCS) are a major risk factor, and centrally‐mediated respiratory depression may increase the risk further. Here, we determined the volume and microstructure of the amygdala, a key structure that can trigger apnea in people with focal epilepsy, stratified by the presence or absence of FBTCS, ictal central apnea (ICA), and post‐convulsive central apnea (PCCA).

Methods

Seventy‐three patients with focal impaired awareness seizures without FBTC seizures (FBTCneg group) and 30 with FBTCS (FBTCpos group) recorded during …

Cortical Thickness Is Related To Variability In Heritage Bilingual Language Proficiency, My V H Nguyen, Kelly A Vaughn, Hannah Claussenius-Kalman, Pilar Archila-Suerte, Arturo E Hernandez

Faculty, Staff and Student Publications

Research suggests that bilingual experience is associated with gray matter changes, such that initial language gains are associated with expansion and language expertise is associated with renormalization. Previous studies on language proficiency development primarily focused on between-subjects, quasiexperimental comparisons of monolinguals and bilinguals. This study proposes a new paradigm to examine language expertise and cortical thickness within heritage bilinguals (
